Abstract
Functional Analytic Psychotherapy (FAP) and the Life Snapshot Inventory (LSI) agree with a contextual, behavioral, relational approach to psychotherapy in which therapists focus on what happens in a session between the client and therapist to shape the interpersonal behaviors, emotional awareness, and self-expression necessary for clients to create and maintain close relationships and to live meaningful lives. This study aimed to test the reliability and the convergent validity of the (LSI) as a self-report instrument to measure meaningful personal and social factors. It was created in Functional Analytic Psychotherapy for use in various areas of life (e.g., family, work, love, spirituality, sexuality, health, etc.). This study involved 393 Jordanian participants (M = 49 years) in the sample. The examined questionnaire was compared with the Depression, Anxiety and Stress Scale-21 Items (DASS-21) and the Rosenberg Self-Esteem Scale (RSES) to examine its validity. The results demonstrated a high internal consistency (α = 0.92) of the LSI, with a correlation ranging between 0.74 and 0.87, both of which were statistically significant. Further, the factorial analysis identified only one factor (45.31% variance). Additionally, the results showed that both the DASS-21 and treatment options had an effect on the total scores of the LSI and the RSES. The LSI was introduced as the predictor and the variable related to depression, anxiety, stress, and the RSES as the dependent variables. The scale in total explained −31% of the variance in depression, −30% of the variance in anxiety, −22% of the variance in stress, and 46% of the variance in RSES. However, the results did not show any effects on the variables of gender, employment, and qualification. The examined questionnaire would be a helpful measure for use in healthcare, diagnosis, and clinical contexts in Jordanian society.
